Introduction

Romeo V2 - a Robot Control Board with Motor Driver (Compatible with Arduino), it is especially designed for robotics applications and extended devices. Romeo benefits from the Arduino open-source platform, it is supported by thousands of open source projects, and can easily be expanded with Arduino compatible Shields. The integrated 2 way DC motor driver and Xbee socket allows you to start your project immediately without the need for an additional motor driver or wireless shield. 
 
Another improvement of Romeo V2 is that it supports stepper motor control. 
 
Romeo V2 - a Robot Control Board with Motor Driver (Compatible with Arduino) behaves like Arduino Leonardo based on the ATmega32u4 chip, You can program it directly from the Arduino IDE 1.0.1 or later version. Because of the ATmega32U4 as it's the sole microcontroller, Romeo V2 is simple and easy to use. The 32U4 chipset handles the USB directly, code libraries are available which allow the board to emulate a computer keyboard, mouse, and more using the very interesting USB-HID protocol!  The best advantage is that ATmega32u4 has two serial ports that allow uploading sketches without removing wireless modules.  Debugging is no longer a painful task. 
 
Version History
  • Romeo V2 also improves the power supply, it has now a switch to select power source either from USB or external power.
  • Romeo V2.2 redesigns the power supply system to improve the stability of the ADC circuit.

Features
*Designed for domestic Arduino fans. Full compatible with Arduino UNO R3.
*Suitable for Arduino Beginners.
*Low-cost main controller board. The main difference from the official one is that this board offers XBee socket and SPI directly-plugged interface, making the best of UART ports. 
*For low-cost project, and Arduino communication module development.
*DFRduino Mega 2560 comes with plenty of IO ports, 54 digital ports, 16 analog ports, and 4 UARTs. 
*Applicable to large projects that require many sensors.
*Mega1280  has as many IO ports as Mega256 but comes with a smaller Flash. Besides, its price is lower than Mega2560.
*Suitable for low-cost projects requiring many sensors.
*Romeo V1 is specially designed for robot fans. It integrates motor driver, all sorts of communication ports, IO expansion port, and so on. 
*Extremely suitable for robot fans.
*The only difference between V1 and V2 is that Romeo V2 adopts ATmega32u4 chip, which provides 2 UARTs, convenient for wireless communication.
*For robot fans to build up projects with wireless communication.
*The first Arduino compatible controller board that integrates Bluetooth 4.0, brings much more flexibility and possibility for Android and IOS mobile development.
*For Android and IOS mobile App BLE developers.
*Integrated CC3000 wifi core and SD card function. Can store a large number of collected data. Compared with Wifi shield, wido is more lightweight and low-cost.

*For IoT developers.
